LETTERING PEN.

Application and February 28, 1925. Serial No. 12,371.

My present invention relates generally to lettering pens, and more particularly toa pen adapted for the broad marking of lettering-lines and to th'e'utilization of ink I as well as water colors and oil paint as lettering mediums, my object being the provision of a simple, inexpensive device of this nature which may be readily filled, effectively utilized and easily and quickly disassembled for cleaning purposes.

' A still further object is the provision of a lettering pen which will be lasting and durable and will not depend upon nibs or "thin metallic and easily injured parts.

In the accompanying drawing which illustrates my present invention and forms part of this specification Figure 1 is a perspective view illustrating the practical application of my inven- 19 tion;

Figure 2 is an enlarged central vertical longitudinal section throughmy improved pen:

Figure 3 is a detailed perspective view of the internal parts removed, and in detached relation.

lieferring now to these figures, myinvention proposes a lettering penincluding an elongated cylindrical barrel 10, which at '30 one end is provided with a ferrule and the likell, the bore-f which is slightly reduced with respect to that of the barrel and the upper inner edge of which is cut away to form a valve seat 12. The lower free edge of this ferrule 11 is rounded transversely and 'circumferentially fluted, this fluted edge being indicated at 13 and being for a purpose which will be presently de scribed.

At its opposite end the barrel is connected to an internally threaded sleeve 14: providing for the reception of the reduced threaded extension 15 of a cap 16, whose edge is preferably knurled as shown, and whose threaded extension 15 has a vertical longitudinal groove 17 the function of which is to permit the escape of air from the upper portion of. the barrel 10 when the cap 16 is screwed downwardly against the upper endof the sleeve 14 after the lettering fluid, indicated at 18, has been poured into the upper end of the barrel 10.

Within the ferrule 11 an applicator 19 is movable axially of thebarrel 10, this appliouter slidably interfitting the ferrule and sixteenth of an inch.

having at its upper inner end an annularly enlarged sloping shoulder 20 forming a valve for engagement outwardly against'the valve seat 12 of the ferrule; Moreover the surface of the applicator 19 belowthle valve 20 has vertical feed grooves 21 at spaced points therearound for the feed of'the lettering' fluid 18 from the barrel 1O v when. the lower end of the applicator 19, which prdjects slightly below the ferrule 11' when valve v20 is seated, 'is placed against the surface upon which the lettering is to be done, with sufiicient pressure .to overcome the tension of a spring 22 which normally holds the valve 20 seated.

Through the barrel 10 an axial stem 23 projects and to one end of this stem the spring 22 is attached. The stem is supported axially of the barrel by spaced guide disks 24 on the stem, which'disks are apertured as plainly shown in Fig. 3 inorder to admit of unobstructed flow of the lettering fluid along and within the barrel. The stem 23 is formed of such length that when placed within the barrel with its spring 22 in en- 30 gagementwith the applicator, the application of the cap 16 and the connection of this cap in effective position, will cause the extension 15 thereof to press against the adjacent end of the stem, forcing the latter lengthwise in order to bring about just 3 the desired tension of spring 22 against the applicator.

In filling the pen for use the cap 16 is first unscrewed and the desired lettering medium, that is paint or ink is poured into i 'the upper end of the barrel to fill, or substantially fill, the reservoir formed within this barrel. The cap .is screwed back in I place and when this is done the pen is ready for use. In using the pen the same is placed. vertically on the surface to be lettered and pressure applied thereto so as to raise or. cause theapplicator 19 to recede about one-' This enables the letterin'g fluid in the reservoir to flow down past the valve seat 12 and through the vertical grooves 21 of the applicator to the surface to be marked, a special value being attached to the circumferential tinting of the lower annular edge of the ferrule 11 of the pen'barrel, the result of which is to permit the paint, ink or water color to spread out evenly from under the lower surface of the applicator l9. no

It is to be understood that the lettering fluid or medium employed will necessitate applicators having vertical grooves 21 of different sizes, larger grooves being necessary where the pen is employed in connection with oil paint or water color than are required where the pen is used with ink. It is obvious that where the medium is to be changed it is an easy matter to disassemble and clean the parts and refill the barrel with the fluid desired.

I claim:

1. A lettering pen including an elongated cylindrical barrel having its ends open and vhaving at one end a ferrule provided with a bore slightly smaller in diameter than the bore of the barrel and forming at its inner end within the barrel a valve seat, the outer circumferential edge of the ferrule being fluted,'a plug or applicator of solid cylindrical form slidably interfitting the bore .of the ferrule having its surfa provided with lengthwise grooves at spaczid points therearound and having its inner end provided with an enlargement forming a valve flange adapted to seat against the inner seat of the ferrule, the outer end of the said plug or applicator being fiat and normally projecting beyond the fluted edge of the ferrule when the valve flange is seated, a screw cap normally closing the opposite end of the barrel, a spring engagin the inner end of the applicator to norma 1y hold the valve flange seated, and an anchor member forming an abutment for the opposite end of the spring and extending through the barrel and normally held in place by the said screw cap.

2. A lettering pen including an elongated cylindrical barrel having its ends open and having at one end a ferrule provided with' a bore slightly smaller in diameter than the bore of the barrel and forming at its inner end within the barrel a valve seat, the outer circumferential edge of the ferrule being fluted, a plug or applicator of solid cylindrical form slidably intertitting the bore of the ferrule having its surface provided with lengthwise grooves at spaced points therearound and having its inner end provided with an enlargement forming a valve flange adapted to seat against the inner seat of the ferrule, the outer end of the said plug or applicator being flat and normally projecting beyond the fluted edge of the ferrule EDGAR COLUMBUS TUGGLE.
